Constraining gamma-ray burst viewing angles with Swift/XRT afterglow light curves
Cheng-Jie Sun, Shuang-Xi Yi, Lin Zhou +6
Gamma-ray bursts (GRBs) are among the most energetic phenomena in the universe, and their afterglow light curves encode information about jet geometry and viewing angle. To constra…
Multi-scale Memory and Regime Shift in the Hyperactive Repeating FRB 20240114A
Wen-Long Zhang, Sheng-Lun Xie, Jun-Jie Wei +5
We present a statistical analysis of FRB~20240114A, a hyperactive repeating fast radio burst, based on 11,553 bursts detected by FAST over 214 days. Our main findings are fourfold.…
Evidence of self-organized criticality in the prompt emission of a bright gamma-ray burst
Wen-Long Zhang, Wen-Jun Tan, Hao-Tian Lan +18
Gamma-ray bursts (GRBs) are the most energetic explosive events in the Universe, yet the physical mechanism of their prompt emission remains a mystery. Especially, it is unclear wh…
Constraining Circum-burst Environments of GRBs with Jet Break Features in X-ray Afterglows
Si-Ji Xin, Yu-Qi Zhou, Sheng-Jin Sun +6
The nature of the circum-burst medium serves as a key diagnostic for probing the progenitor systems and the physics of relativistic jet propagation in gamma-ray bursts (GRBs). In t…
Galactic constraints on spinning primordial black hole dark matter from interstellar dust heating
Shaobin Hu, Yupeng Yang, Chengjie Sun +5
Primordial black holes (PBHs) are compelling dark matter candidates. PBHs with masses between and can heat interstellar dust via Hawking radiation.…
Magnetar-powered long gamma-ray bursts and connection to superluminous supernovae and fast radio bursts
Yu-Qi Zhou, Shuang-Xi Yi, Yu-Peng Yang +4
Based on X-ray afterglow observations from the Swift satellite, we construct a sample of 169 long gamma-ray bursts (LGRBs) exhibiting the canonical magnetar plateau signature, i.e.…
Spectral Hardness as the Primary Discriminator: Unveiling the Collapsar--Merger Boundary with a Gold-Standard Gamma-Ray Burst Sample
Xue Zhang, Yan-Kun Qu, Shuang-Xi Yi +4
In this Letter, we establish a robust, physically motivated classification method using a Support Vector Machine (SVM) trained on a "gold-standard" sample of 24 GRBs with spectrosc…
Exploring the central engines of gamma-ray bursts from prompt light curves
Xue Zhang, Shuang-Xi Yi, Wei-Hua Lei +6
Hyperaccreting stellar-mass black hole systems are leading candidates for the central engines of gamma-ray bursts (GRBs). Their jets are thought to be powered by either the Blandfo…
The Role of Plasma Lensing in Fast Radio Bursts
R. N. Li, Y. B. Wang, S. X. Yi +2
Growing evidence indicates that some fast radio bursts (FRBs) reside in dense, magneto-ionic environments where extrinsic propagation effects can substantially reshape the observed…
Brightest GRB flare observed in GRB 221009A: bridge the last gap between flare and prompt emission in GRB
Zheng-Hang Yu, Chen-Wei Wang, Shao-Lin Xiong +46
Flares are usually observed during the afterglow phase of Gamma-Ray Bursts (GRBs) in soft X-ray, optical and radio bands, but rarely in gamma-ray band. Despite the extraordinary br…
